This graph shows that as of 1962, about 46 percent of adults in the United States fell into the categories of overweight, obesity, and extreme obesity. About 32 percent of adults were overweight, about 13 percent were obese, and about 1 percent had extreme obesity.

Percentages of adults within all of these categories increased gradually until the late 1970s, at which point they began to climb more quickly, leveling off somewhat around 2000. The increase was most dramatic within the obesity category, while the percentage of overweight adults held fairly steady, and the percentage of adults with extreme obesity increased moderately. Around 2000, about 70 percent of adults were considered overweight, obese, or extremely obese. Of this group, 34 percent were considered overweight, about 31 percent were considered obese, and about 5 percent were considered to have extreme obesity.

By 2010, the percentage of adults considered overweight, obese, or extremely obese had climbed to about 75. About 33 percent were considered overweight, about 36 percent were considered obese, and about 6 percent were considered extremely obese.
